Vision provides a rich collection of information about our environment. The difficulty in vision arises, since this information is not obvious in the image, it has to be actively constructed. Whereas earlier algorithms have favored a bottom-up approach, which converts the image into an internal representation of the world, more recent algorithms search for alternatives and develop frameworks which make use of top-down connections. Following the latter line of research, I outline an approach according to which perception is an active process: planning stages in the frontal areas modify perception in early stages to construct the needed information from the environmental input. A large-scale model demonstrates this concept on natural scene perception.
